UPDATE: Another profile that scales and doesn’t flicker is Company of Heroes, RelicCOH.exe. It might even be a bit faster than Dark Void’s.

After a fair amount of testing, the Dark Void profile gives the performance boost of the FEAR profile without the flickering.

So what you need to do is grab RadeonPro so you can make a profile for the game. You can’t simply do the exe rename trick, as it has a launcher that blocks you from starting from the game exe directly.

Once inside RadeonPro, push the ‘add a new profile’ button and select S9-Win32-F.exe from the Binaries/Win32 folder of the game. Go to the tweaks tab and click ‘manage custom profiles’, then add Dark Void as ‘ShippingPC-SkyGame.exe‘. Now to fix the launcher issue, go to the launcher tab and select ‘Games for Windows Live’ from the dropdown, then pick the actual launcher exe, which is S9.exe in the root folder of the game.
